W-like bound entangled states and secure key distillation
Remigiusz Augusiak, Pawel Horodecki
We construct multipartite entangled states with underlying W-type structure satisfying positive partial transpose (PPT) condition under any (N-1)|1 partition. Then we show how to d…
Entanglement-redistribution boxes
Andrzej Grudka, Michal Horodecki, Pawel Horodecki +2
We establish a framework to study the classical-communication properties of primitive local operations assisted by classical communication which realize various redistributions of…
Sub-- and super--fidelity as bounds for quantum fidelity
J. A. Miszczak, Z. Puchała, P. Horodecki +2
We derive several bounds on fidelity between quantum states. In particular we show that fidelity is bounded from above by a simple to compute quantity we call super--fidelity. It i…
Note on genuine multipartite classical correlations
Andrzej Grudka, Michal Horodecki, Pawel Horodecki +1
We discuss the problem of coexistence of genuine quantum multipartite correlations and classical multipartite correlations. We introduce a postulate which any measure of genuine mu…
